What does "G-code" refer to in CNC machining?

G-code, also known as "Geometric code," is indeed a language used to instruct CNC (Computer Numerical Control) machines on how to perform specific tasks. It comprises a series of commands or instructions that dictate the movements and actions of the machine, such as the speed, feed rate, and path of the tool. By using G-code, operators can control the precision of machining operations, allowing for complex and detailed workpiece fabrication.

In CNC programming, the G-code commands enable the machine to understand exactly what movements to make, which tools to use, and how to execute the machining process efficiently. This instruction set is essential for translating design plans into actionable steps, ensuring accuracy and repeatability in the manufacturing process.

Understanding G-code is crucial for anyone involved in CNC machining, as it forms the foundational language for machine operation, allowing for a wide variety of tasks from drilling to milling and turning.
